Applications for Human Kallikrein 2 Antibody

Application
Recommended Usage

Immunoprecipitation

25 µg/mL
Sample: Conditioned cell culture medium spiked with Recombinant Human Kallikrein 2 (Catalog # 4104-SE), see our available Western blot detection antibodies

Western Blot

1 µg/mL
Sample: Recombinant Human Kallikrein 2 (Catalog # 4104-SE).

Neutralization

Measured by its ability to neutralize Recombinant Human Kallikrein 2 (2 µg/mL, Catalog # 4104-SE) cleavage of the fluorogenic peptide substrate PFR-AMC (0.1 mM). The Neutralization Dose (ND50) is typically 3.4 µg/mL.

Background: Kallikrein 2

Kallikrein 2 (KLK2) is a secreted serine protease that is highly expressed in the human prostate gland (1). It is also known as the prostate-specific glandular kallikrein. The enzyme is highly specific for cleavage after arginine residues. KLK2 is able to activate the urokinase-type plasminogen activator (2). KLK2 is inhibited by serpins such as protein C inhibitor, antichymotrypsin, and plasminogen activator inhibitor 1 (3‑5). KLK2 is structurally related to KLK3, the prostate-specific antigen (PSA). Like PSA, KLK2 is considered to be a biomarker for prostate cancer (6).
